Predicted to be involved in positive regulation of proteasomal ubiquitin-dependent protein catabolic process; protein polyubiquitination; and regulation of skeletal muscle fiber development. Predicted to act upstream of or within several processes, including nucleocytoplasmic transport; positive regulation of ubiquitin-dependent protein catabolic process; and regulation of myotube differentiation. Predicted to be located in cytoplasm and nucleus. Orthologous to human FBXO22 (F-box protein 22). [provided by Alliance of Genome Resources, Apr 2022]
